T all whom it may concern:

Be it known that I, WALTER PASTURCZAK, a citizen of Poland, residing at Fairmont, in the county of Marion-and State of? Test Virginia, have invented certain new and useful Improvements in Roundabouts', of which the following is a specification.

This invention relates to certain new "and useful improvements in roundabouts adapted toprovide a simplified and durable form 'ofamusement device by means of which pleasure rides may be given to children.

' The invention aims to provide a de'vi ceof the above kind of generally simple anddurable constructioninvolving meansof' a desirable nature for producingmusical sounds when the device is in operation.

Another object is to generally simplify and improve various parts of the device.

With the above generalob'jects in view and others that will appear as the'nature of the invention is better unders toodpthe invention consists in thenoveil form, combination and arrangement of parts hereinafter more fullydescribed inconnection ,with the accompanying drawings, in which like reference characters indicate similar parts throughout the views In the drawings, v

Figure 1 is a view partly in side elevation and partlyin vertical'section of a roundabout constructed-in accordance with the,

present invention,

Figure 2 is a horizontal sectional View partly broken away and taken substantially upon line 2-2 of Figure '1,

Figure 3 is a horizontal sectional view taken substantially upon line 3-3 of Figure 1 and drawn on a larger scale, Figure 4: is an enlarged horizontal sectional view taken substantially upon line ki of Figure 1 s Figure 5 is a view similar to Figure 4 taken upon line 5-5 of Figure-1,

Figure G is anenlarged fragmentary view in-vertical section on line 66- of Figured, Figure 7 is a side-elevational view. of the baby jumper and its supporting arm and Figure 8 is a-viewsimilar toFigure/4- of the carand its supporting arm.

Referring more in detail to-the several views, the present invention embodies a platform 5 having suitable supporting legs -6 and provided with a oentral opening 7 through which the power shaftc8'-of= a.su1table motor 9 rotatably projects. The motor I struction.

9may beofthe usualispring type having a I winding, handle 11,0 and embodying a" casing rigidly securechtotheundr surface of" the platform 5 'with'the power 'shaft'8proj ecti'ng n1 wardly through. the opening in a vertical position. 1

v The upper endfof'r the shaft8'is provided with a screwthread'ed"socket and'anoth er' vertical-{shaft 1'1 has'its lower end-threaded into this sook'efi as generally denoted by; the

numeral 12 so that rotation ofthe'slraft' 8 i will cause"rotation of the shaft" 11.

'The upper endfof,thfe-'shait llfiextends freely through the top plate 12" of a tripod or similar-supportingstructure which also embodiesaplurality oflegs 13" hingedas at 13"near= their upper' ends" to the edge of the plate 12" the-le.gs*13 extending-downwardly 1n diverging relation to also engagethe surface-"upon which; the legs -6 rest. By-means of this tripod; the sh'aft'll is. steadied and held againstlateral strains at itS upper e'n'd.

The-legs 13; are-normally spreaded'by'ineans of suitable springs- 14 which may he attaehed-*-to the under surface ofthe plate 12' and v disposed with their-"free ends Y bearing against the inner edges of the legs: 13; As

indicated'in Figure-6; the plate '12 is provided with peripheral-notches 15 in which the upper ends of -the legs 13- are positioned to provide a more rigidand du-rable conf A disk 16 is attached to the-power shaft 8 and rotatably disposediini a horizontal position ina clrcular recess ln -the upper surface of the platfonm'o as shown in Figure-1, and

said disk '16 is interlooked as at 17- with another disk- 18 that is rigidly secured on the lowerend of a :hollow standard 19 through which the-shaft: ll extendsy It willthus be seen that rotation: of'ithe shaft 8 will thus be imparted mtbe hollow standard l9 The standard! 19 terminates in; proximity to the under surface of th'e plate. 12'-andi*is provided intermediate its-ends witha plurality of radially' projecting arms, two of which. arespreferahly (employed as at 20' and 21. The arm 20wrigidly supports thehor-i- .zontal: guardrail :22 iof a baby jumper involvingv a foldable;-seat*23 yieldingly suspended by means of helicaltension springs 1 24 from the; forward part of the guardz'rail-i 22 and the arm 20-.

A suitable car 25} somewhatwsimilar in form to the'body 'ofx-a go-oart =isisuspende'd from the other arm 2l-by means of:=diverg- .ring in such manner as to permit rotation of the standard 19 in the proper direction by means of the motor 9 while preventing rotation of said standard in the opposite direction.

A bell-shaped drum 29 is suitably fastened upon the upper end of the shaft 11 above the plate 12 so that its depending rim extends toward and in close proximity to said plate 12 in position to be engaged by a suitable brake shoe 30 which is fastened upon a lateral arm. 31 rigid with a pivoted lever 32 having its inner end pivoted as at 33 on the plate 34; which is rigidly fastened on the upper surface of the plate 12 as shown clearly in Figure 5. A helical tension spring 35 has one end attached to a post 36 carried by the plate 12 and has its other end attached as at 37 to a lug on the arm 31 of the lever 32. The hub portion of the lever 32 is provided with a pair of stop lugs 38 arranged to engage opposite sides of the post 36, and the spring 35 extends across the pivot v33 at one'side of the center of said pivot when the shoe 30 is disengaged from the brake drum 29 and one of the lugs 38 engages the post 36 as shown in Figure 5. Also, when the lever 32 is swung to engage the other lug 38 with the post 36, the spring 35 willmove past the center of the pivot to the opposite side of said center and in this way the spring 35 serves to yieldingly hold the brake shoe 30 in either engaged or disengaged position.

In order to provide musical sounds automatically as the standard 19 is rotated, a circular hollow body 39 of a stringed musical instrument is secured on the upper portion iofsaid standard 19 with its strings 40 in position to be successively engaged by a depending vertical pick 41. rigidly fastened to the under surface of the plate 12 near the edge of the latter. This stringed musical instrument has its strings adjusted to the proper tone by means of a. plurality of tuning pegs 12 arranged at the margin of the body 39 in the circular series, the strings 40 being radially disposed as shown .in Figure 4 with their inner ends attached to a ring 43 surrounding the standard 19.

In operation, the motor 9 is started in any preferred or well known manner so as to drive the shaft 8 and, through the connections described, this will cause the shaft 11 and standard 19 to be rotated together with the parts carried thereby including the brake drum 29; arms 20 and 21; baby jumper 24; car body 25; and the body 39 and strings 40 of the musical instrument.

' At this time, the platform and the tripod remain stationary. When rotation of the standard 19 takes place the strings 40 successively engage the pick 41 for producing musical sounds and thus amusement is afforded to children seated in the car 25 and in the baby jumper. The car 25 is provided for younger children while older children may use the baby jumper, the seat 23, of which will sway and yield vertically from centrifugal action and other causes as the arms 20 and 21 rotate. Whenever it is desired to stop the roundabout, the motor 9 will be rendered inoperative and the brake shoe 30 applied. In this way, the device will be brought to a gradual stop and the pawl 28 will prevent backward rotation of the parts which is desirable particularly when the children are placed in the baby jumper and car or taken out of the same.

From the foregoing description, it is be lieved that the construction and operation of the present invention will be readily understood and appreciated by those skilled in the art.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.
